- 2. Related Art
- In a conventional electronic device having a display unit and an operation unit, when an operation unit is operated in a state where a standby screen is displayed on the display unit, characters of different character kinds assigned to the operation unit are input into the electronic device and displayed in different regions in the display unit. Moreover, the electronic device launches a selected application in a state where the displayed characters are inputted by selecting a desired application from a menu for a plurality of applications in a state where inputted characters are displayed on the display unit (for example, refer to JP2007-200243A and JP2009-032209A).
- However, in the electronic devices described in JP2007-200243A and JP2009-032209A, in many cases, characters of different character kinds are displayed in the display screen of the display unit by splitting the display screen into two upper and lower sides in both the state where the display screen of the display unit is used vertically and the state where the display screen is used horizontally. Therefore, in the state where the display screen of the display unit is used horizontally, the view point movement distance of the user is long when the user views both character strings of different character kinds, thus spoiling the operability.
- An object of the present invention is to provide a mobile electronic device and a character input method, which can shorten a view point movement distance of the user even in a state where the display screen of the display unit is used horizontally.
- In order to solve the above problems, the mobile electronic device according to the present invention includes: a display unit having a display screen of a substantially rectangular shape; an operation unit having a plurality of operation keys to which at least a first character kind character and a second character kind character are assigned; and a control unit which, when one operation key is operated among the plurality of operation keys, displays the first character kind character and the second character kind character assigned to the operated operation key on the display screen; in which in a state where the display screen is used horizontally, the control unit displays the first character kind character left aligned on an upper side of the display screen and displays the second character kind character right aligned on a lower side of the display screen; and when a predetermined operation is performed with the operation unit, the control unit continues the display of either one of the first character kind character and the second character kind character on the display screen while maintaining the display position and deletes the display of the other one of the first character kind character and the second character kind character.
- In addition, it is preferable if, when an operation that adopts the display of the second character kind character is performed as the predetermined operation, the control unit deletes the display of the first character kind character and displays the display relating to the second character kind character right aligned while maintaining the display position of the second character kind character on the display screen.
- In addition, it is preferable if, when an operation to display the second character kind character is performed with the operation unit, the control unit displays a single color display in an entire display region where the first character kind character is displayed while maintaining the display position of the second character kind character on the display screen.
- In addition, it is preferable if, when an operation that adopts the display of the first character kind character is performed as the predetermined operation with the operation unit, the control unit deletes the display of the second character kind character and displays the display relating to the first character kind character on the entire width display screen while maintaining the display position of the second character kind character on the display screen.
- In addition, it is preferable if the control unit splits the display screen into right and left sides, and displays the first character kind character left aligned on an upper part of the split left side display screen, and displays the second character kind character right aligned on a lower part of the split right side display screen.
- In addition, it is preferable if the control unit splits the display screen into upper and lower sides, and displays the first character kind character left aligned on an upper part of the split upper side display screen, and displays the second character kind character right aligned on a lower part of the split lower side display screen.
- In addition, it is preferable if the operation unit includes a call making key for making a call, and when the call making key is operated as the predetermined operation, the control unit deletes the display of the first character kind character while maintaining the display position of the second character kind character in the display screen.
- In addition, it is preferable if, after the display of the other one of the first character kind character and the second character kind character is deleted while maintaining the display position of one of the first character kind character and the second character kind character on the display screen, when an operation to delete a part of the maintained character string of the first character kind character or the second character kind character is performed with the operation unit, the control unit returns the state to a state where both the first character kind character and the second character kind character are displayed on the display screen.
- In order to solve the above problems, the character input method in a mobile electronic device including a display unit having a display screen of a substantially rectangular shape, and an operation unit, according to the present invention includes: a step of displaying, when one operation key is operated among a plurality of operation keys of the operation unit, a first character kind character and a second character kind character assigned to the operated operation key on a display screen of the display unit; a step of displaying, in a state where the display screen is used horizontally and both the first character kind character and the second character kind are displayed on the display screen, the first character kind character left aligned on an upper side of the display screen, and the second character kind character right aligned on a lower side of the display screen; and a step of continuing, when a predetermined operation is performed with the operation unit, the display of one of the first character kind character and the second character kind character on the display screen performed while maintaining the display position, and deleting the display of the other one of the first character kind character and the second character kind character.

cellular telephone device 1 that serves as a mobile electronic device will be described with reference toFIGS. 1 to 3 .FIG. 1 is a front view of thecellular telephone device 1 in an open state.FIG. 2 is a side view of thecellular telephone device 1 in an open state.FIG. 3 is a front view of thecellular telephone device 1 in a cross state. - As shown in
FIGS. 1 to 3 , thecellular telephone device 1 of this embodiment comprises: an operationunit side case 2 that serves as a first case; and a displayunit side case 3 that serves as a second case. - External surface of the operation
unit side case 2 is constituted by afront case 2 a and arear case 2 b. The operationunit side case 2 is configured so that anoperation unit 11, and amicrophone 12 to which voice of the user of thecellular telephone device 1 is inputted are exposed to thefront case 2 a side. - The
operation unit 11 comprises: a functionsetting operation key 13 for actuating various functions such as various settings, a directory function, and an e-mail function; aninput operation key 14 for inputting, for example, numeric characters of a telephone number and characters of e-mails or the like; and adetermination operation key 15, that serves as an operating member, which performs operations such as determination in various operations, and scrolling in up, down, right-left directions. A predetermined function is assigned to each of the keys which constitute theoperation unit 11 according to the opening and closing state of the operationunit side case 2 and the displayunit side case 3, various modes, or kinds of the launched application or the like (key assigning). Moreover, by the user pressing a respective key, an action according to a function assigned to the key is executed. - The external surface of the display
unit side case 3 is constituted by afront case 3 a and arear case 3 b. On thefront case 3 a of the displayunit side case 3, adisplay unit 21 for displaying a variety of information and aspeaker 22 which outputs voice of the other party of a telephone call are arranged so as to be exposed to the outside. Here, thedisplay unit 21 is constituted by components such as: a liquid crystal panel; a drive circuit for driving the liquid crystal panel; and a light source unit such as a back light unit, which irradiates light from the back side of the liquid crystal panel. - The operation
unit side case 2 and the displayunit side case 3 are connected openably and closably via an connectingpart 4. Specifically, the connectingpart 4 is constituted by: ahinge mechanism 4 a; a supportingpart 4 b; and arotation mechanism 4 c. - As shown in
FIG. 2 , the end part of the operationunit side case 2 at the connectingpart 4 side and the supportingpart 4 b are connected via thehinge mechanism 4 a. The displayunit side case 3 and thehinge mechanism 4 a are connected via the supportingpart 4 b. The supportingpart 4 b and the displayunit side case 3 are connected via therotation mechanism 4 c. Thereby, thecellular telephone device 1 connects the operationunit side case 2 and the displayunit side case 3 via thehinge mechanism 4 a, the supportingpart 4 b, and therotation mechanism 4 c, and is configured such that the operationunit side case 2 and the displayunit side case 3 can be relatively moved and the displayunit side case 3 and the supportingpart 4 b can be relatively moved. - That is, the
cellular telephone device 1 can be in: a state where the operationunit side case 2 and the displayunit side case 3 are opened and where the longitudinal direction of the operationunit side case 2 and the longitudinal direction of the displayunit side case 3 are substantially identical (open state); a state where the operationunit side case 2 and the displayunit side case 3 are folded together (closed state); and a state where the longitudinal direction of the displayunit side case 3 and the longitudinal direction of the displayunit side case 3 cross with each other forming a predetermined angle (for example, substantially 90 degrees) by rotating the displayunit side case 3 against the supportingpart 4 b about a rotation axis Z (cross state). - Here, a closed state is a state where the operation
unit side case 2 and the displayunit side case 3 face and overlap with each other. An open state is a state where the operationunit side case 2 and the displayunit side case 3 do not overlap with each other. A cross state is a state where a relative position of the displayunit side case 3 to the supportingpart 4 b is changed from the open state. Thus, the connectingpart 4 connects the operationunit side case 2 and the displayunit side case 3 so that the state changes between the open state or the cross state, and the closed state. - In addition, detection of the open state, the closed state, and the cross state can be performed using a hall device and a magnetic part (both of which are not illustrated), for example. Specifically, the hall device and the magnetic part are spaced apart from each other in the open state and the cross state, and arranged so that the hall device and the magnetic part overlap with each other in the thickness direction of the case in the closed state. Since the distances between the hall device and the magnetic part are different among the open state, the closed state, and the cross state at this time, strength of the magnetic force lines radiating from the magnetic part to the hall device is also different. Thus, the hall device detects the open state, the closed state, and the cross state in the
cellular telephone device 1 using the strength (magnitude of the magnetic force) of the magnetic force line radiated from the magnetic part. - In addition, as shown in
FIG. 2 , a side key 2 c is formed at the side surface of the operationunit side case 2. The function of the side key 2 c will be described later. -
FIG. 4 is a functional block diagram showing functions of thecellular telephone device 1. In thecellular telephone device 1, as shown inFIG. 2 , the operationunit side body 2 includes the operation unit (input unit) 11, themicrophone 12, amain antenna 40, anRF circuit unit 41, adisplay control unit 42, asound processing unit 43,memory 44, and acontrol unit 45. In thecellular telephone device 1, the displayunit side body 3 includes thedisplay unit 21, thereceiver 22, and adriver IC 23. - The
main antenna 40 communicates with a base station or the like via a first usable frequency band (for example, 800 MHz), and is configured as a dual band compatible antenna that is compatible with a second usable frequency band (for example, 1.5 GHz) for GPS communication. It should be noted that, although 800 MHz is set as the first usable frequency band in the present embodiment, other frequency bands can also be used. Moreover, themain antenna 40 may communicate with an external device via the first usable frequency band, and another antenna compatible with the second usable frequency band for GPS communication may be separately provided. - The
RF circuit unit 41 performs demodulation processing of a signal received via themain antenna 40, and transmits the processed signal to thecontrol unit 45. TheRF circuit unit 41 performs modulation processing of the signal transmitted from thecontrol unit 45, and transmits the signal to external devices (base stations) via themain antenna 40. In addition, on the other hand, theRF circuit unit 41 notifies thecontrol unit 45 of the intensity of a signal received via themain antenna 40. - The
display control unit 42 performs predetermined image processing according to control by thecontrol unit 45, and outputs the processed image data to thedriver IC 23. When the image data is transmitted from thedisplay control unit 42, thedriver IC 23 stores the image data in frame memory, and outputs the image data on thedisplay unit 21 at predetermined timing. - The
sound processing unit 43 performs predetermined sound processing according to control by thecontrol unit 45 on a signal transmitted from theRF circuit unit 41, and outputs the processed signal to thereceiver 22 or a speaker (not shown). Thereceiver 22 outputs the signal that is transmitted from thesound processing unit 43, to the outside. - Furthermore, when a signal is input from the
microphone 12, thesound processing unit 43 processes the signal according to control by thecontrol unit 45, and outputs the processed signal to theRF circuit unit 41. TheRF circuit unit 41 performs predetermined processing on the signal transmitted from thesound processing unit 43, and outputs the processed signal to themain antenna 40. - The
memory 44 includes, for example, working memory, and is utilized for arithmetic processing by thecontrol unit 45. Moreover, thememory 44 stores a plurality of applications as well as a variety of tables and the like, required by the applications. In addition, thememory 44 may also serve as detachable external memory. - The
control unit 45 controls the entirety of thecellular telephone device 1, and is configured to employ a central processing unit (CPU) and the like. Here, a description is provided for control operations of thecontrol unit 45 depending on key operations via theoperation unit 11. Thecontrol unit 45 changes the characters and functions to be assigned to each key (the functionsetting operation keys 13, theinput operation keys 14 and the selection key 15) configuring theoperation unit 11, essentially in accordance with an application that is currently activated. - More specifically, when any key is depressed, the
operation unit 11 transmits position information of the key to the control unit 45 (for example, as shown inFIG. 5( a), in a case of depressing a key in the second line and the left row among the input operation keys 14 (a key with “1” and “a” printed on its surface, position information of (X2, Y2) is transmitted). Thecontrol unit 45 accesses thememory 44, refers to a key assignment table corresponding to an application that is currently activated, and executes processing of a character and a function assigned thereto, based on the position information that has been transmitted from theoperation unit 11. For example, as shown inFIGS. 5( b) to 5(d), thememory 44 stores a plurality of key assignment tables. It should be noted thatFIG. 5( b) is a table that is utilized when an outgoing telephone call is made;FIG. 5( c) is a table that is utilized in a memo pad application and a mail application; andFIG. 5( d) is a table that is utilized when changing a channel, in a television tuner application. - It should be noted that execution of processing of a character means that, for example, in a case in which the currently activated application is a memo pad application, “1” or “a” is displayed on the
display unit 21. Furthermore, execution of processing of a function means that, for example, in a case in which the currently activated application is a television tuner application, the display channel is set tochannel 1. - Moreover, the
memory 44 stores a plurality of key assignment tables. Depending on the application, thecontrol unit 45 switches a key assignment table to be referred to, refers to a predetermined key assignment table based on position information of a key that has been transmitted from theoperation unit 11, and performs predetermined processing. - In a
cellular telephone device 1 configured as such, there is Application Y, wherein when a key is operated in a communication standby state, each of a plurality of codes (for example, a numeric character and a character) assigned to the operated key are displayed on, for example, separate screen areas, in parallel, and when a predetermined key operation is performed, a screen where one of the codes is displayed is enabled. In addition, Application Y may display one code (for example, character) among the plurality of codes assigned to the operated key when a key is operated in a communication standby state. - In addition, in the
cellular telephone device 1, Application Y has a function to display conversion candidates for the character string inputted with theoperation unit 11, or prediction candidates that follow the character string. Furthermore, Application Y has a function to execute an application when a character string indicating a name of the application or processing contents of the application is inputted as a result of the conversion candidate or prediction candidate being selected. - Next, processing by the
control unit 45 according to this embodiment will be described with reference toFIG. 6 andFIG. 7 .FIG. 6 andFIG. 7 are diagrams showing examples of screen transfers displayed on the display screen of thedisplay unit 21 according to this embodiment. - When one operation key is operated among a plurality of operation keys of the
operation unit 11 in a state where the display screen of thedisplay unit 21 is used horizontally, thecontrol unit 45 according to this embodiment displays the first character kind character left aligned on an upper side of the display screen, and displays the second character kind character right aligned on a lower side of the display screen. When a predetermined operation is performed by theoperation unit 11, thecontrol unit 45 maintains the display of either one of the characters of the first and the second character kind characters on the display screen, and deletes the other one of the first character kind character and the second character kind character, according to the operated action. - Specifically, as shown in
FIG. 6( a), when the plurality of operation keys of theoperation unit 11 are operated in the state where the display screen of thedisplay unit 21 is used horizontally, thecontrol unit 45 splits the display screen into upper and lower sides, and displays a alphabetic character assigned to the operation key thus operated (“dav” in this example) in a region Al on the upper side, and displays a numeric character assigned to the same operation key (numeric characters “32888” in this example) in a region B1 on the lower side, with Application Y. - In addition, the

For example, the soft keys S3 and S5 are associated with the functionsetting operation keys key operation keys 13 of theoperation unit 11, and the soft key S4 is associated with the determination operation key 15 a of theoperation unit 11. When the function setting operation key 13 a or 13 b or the determination operation key 15 a is pressed, the function corresponding to the respective display of soft keys S3 and S5 is executed. In addition, when the determination operation key 15 a is pressed, the last performed operation is confirmed. It should be noted that, the key S1 is, for example, a key shown in (X1, Y1) inFIG. 5 , and key S2 is, for example, one of the functionsetting operation keys 13 inFIGS. 1 and 3 (for example, a key located at lower right among the four function setting operation keys 13). In addition, a soft key is a key for assigning a function that changes as needed and is displayed in a region imitating a button. - In
FIG. 6( a), when an operation that selects the soft key S4 is performed with thedetermination operation key 15 for displaying the alphabetic character, thecontrol unit 45 deletes the display of the numeric character string “32888” from the region B1 while maintaining the display position of the alphabetic character string “dav” in the region A1, and displays a display related to the hiragana character string on the entire width display screen (a region C1 inFIG. 6( b)), that is, the alphabetic character string “dav”, conversion candidates of the hiragana character string, and the soft keys S3, S4 and S5 are displayed (refer toFIG. 6( b)). - Meanwhile, in
FIG. 6( a), when an operation for selecting key S2 is performed for making a call, thecontrol unit 45 deletes the display of the alphabetic character string, and displays a display related to the numeric character string, that is, the numeric character string “32888”, right aligned in the display screen (refer toFIG. 6( c)). - In particular, as shown in
FIG. 6( c), when an operation for selecting key S2 is performed with thedetermination operation key 15 for making a call, thecontrol unit 45 displays a single color display (for example, blackout and grayout) on the entire display region where the alphabetic character string is displayed (region D1 inFIG. 6( c)) while maintaining the display position (right aligned position) of the numeric character string “32888”. - In addition, the
control unit 45 displays soft keys S6 and S7 on a lower side of region E1 in the display screen (region F1). Here, the soft key S6 is used for going back to the previous screen, and the soft key S7 is used for confirming various operations to the character string displayed in the region E1 in the display screen. Each of the soft keys S6 and S7 is associated with an operation key of theoperation unit 11. For example, the soft key S6 is associated with the functionsetting operation key 13 of theoperation unit 11, and the soft key S7 is associated with thedetermination operation key 15 of theoperation unit 11. When the functionsetting operation key 13 is pressed, the screen goes back to the previous screen. In addition, when thedetermination operation key 15 is pressed, the previous operation is confirmed. - Although
FIG. 6 describes an example in which the display screen is split into upper and lower sides, the display screen may be split into right and left sides as shown inFIG. 7 . That is, as shown inFIG. 7( a), when the plurality of operation keys of theoperation unit 11 are operated in the state where the display screen of thedisplay unit 21 is used horizontally, thecontrol unit 45 splits the display screen into right and left sides, and displays the alphabetic character string “dav” assigned to the operation keys, in a region H1 on the left side left aligned, and displays the numeric character string “32888” assigned to the operation keys, in a region J1 on the right side right aligned. - In addition, in the region H1 in the display screen, the
control unit 45 displays with application Y: thesoft key 3 for changing the character kind of the character string displayed in the region H1 in the display screen; the soft key S4 for confirming various operations to the character string displayed in the region H1 in the display screen; and the soft key S5 for displaying various functions to the character string displayed in the region H1 in the display screen. - In addition, the
control unit 45 displays a plurality of keys S1 and S2 that relate to functions that use the numeric character string displayed in the region B1 in the display screen, with Application Y. Here, the key S1 is a key for making a call using the numeric character string displayed in the region J1 with a telephone application, and the key S2 is a key for registering into the directory the numeric character string displayed in the region J1 with a directory application. - In
FIG. 7( a), when an operation for selecting the soft key S4 is performed with thedetermination operation key 15 for displaying the alphabetic character string, thecontrol unit 45 deletes the display of the numeric character string “32888” from the region J1 while maintaining the display position of the character string of the alphabetic character string “dav” in the region H1 to perform the display related to the alphabetic character string on the entire width display screen (region K1 inFIG. 7( b)), that is, the alphabetic character string “dav”, the conversion candidates of the alphabetic character string, and the soft keys S3, S4 and S5 are displayed(refer toFIG. 7( b)). - Meanwhile, as shown in
FIG. 7( a), when an operation that selects key S2 is performed with thedetermination operation key 15 for making a call, thecontrol unit 45 deletes the display of the alphabetic character string, and displays the display related to the numeric character string, that is, the display of the numeric character string “32888”, in the display screen right aligned (refer toFIG. 7( c)). - In particular, as shown in
FIG. 7( c), when an operation for selecting key S2 is performed with thedetermination operation key 15 for making a call, thecontrol unit 45 displays a single color display (for example, blackout and grayout) at the entire display region where the alphabetic character string is displayed (region M1 inFIG. 7( c)) while maintaining the display position of the numeric character string “32888” in the display screen. In addition, thecontrol unit 45 displays the soft keys S6 and S7 on a lower side of region N1 in the display screen (region P1). - In addition, after maintaining the display position of one of the alphabetic character string or the numeric character string and deleting the display of the other one of the alphabetic character string or the numeric character string in the display screen in
FIG. 6( b) and (c) orFIG. 7( b) and (c), when an operation to delete a part of the character string of either the alphabetic character string or the numeric character string is performed by theoperation unit 11, thecontrol unit 45 may delete a part of the character string of either the alphabetic character string or the numeric character string and display both the alphabetic character string and the numeric character string that are not deleted on the display screen. - Specifically, when an operation to delete a character “v” in the alphabetic character string “dav” or a numeric characters “888” is performed with
operation unit 11 inFIG. 6( b) orFIG. 6( c), thecontrol unit 45 deletes the alphabetic character “v” and the numeric characters “888”, and splits the display screen into upper and lower sides, and displays the alphabetic character string “dav” left aligned on the upper side in the display screen, and displays the numeric character string “32” right aligned on the lower side in the display screen. - Alternatively, when an operation to delete a character “v” among the alphabetic character string “dav” or the numeric character “5” is performed with the
operation unit 11 inFIG. 7( b) orFIG. 7( c), thecontrol unit 45 deletes the alphabetic character “v” and the numeric character “888”, and splits the display screen into right and left sides, and displays the alphabetic character string “da” left aligned on the left side in the display screen and displays the numeric character string “32” right aligned on the right side in the display screen. -
FIG. 8 is a flow chart showing internal processing of thecontrol unit 45 according to this embodiment. In Step S1, thecontrol unit 45 detects that one operation key is operated in a standby screen among a plurality of operation keys in theoperation unit 11. It should be noted that the standby screen is also referred to as wallpaper, and is a screen that awaits making and reception of a call and launching of an application. In Step S2, thecontrol unit 45 launches Application Y described above. - In Step S3, the
control unit 45 determines whether or not themobile telephone 1 is in an open state or a cross state, that is, whether or not the display screen of thedisplay unit 21 is used vertically or horizontally. If the display screen is used horizontally (YES), the process proceeds to Step S4. If the display screen is used vertically (NO), the process ends. - In Step S4, the
control unit 45 determines whether or not the setting is performed so that the display screen is split into upper and lower sides. If the setting is performed to split the display screen into upper and lower sides (YES), the process proceeds to Step S5. If the setting is performed to split the display screen into right and left sides (NO), the process proceeds to Step S11. - In Step S5, the
control unit 45 splits the display screen into upper and lower sides, and displays the alphabetic character string assigned to the operation key in the region A1 on the upper side and displays the numeric character string assigned to the operation key in the region B1 on a lower side with Application Y (refer toFIG. 6( a)). - In Step S6, the
control unit 45 determines whether an operation for selecting the display of the alphabetic character string or the numeric character string is performed. If an operation for selecting the display of the alphabetic character string is done (YES), the process proceeds to Step S7. If an operation for displaying the numeric character string is done (NO), the process proceeds to Step S8. - In Step S7, the
control unit 45 deletes the display of the numeric character string from the region B1, and displays the display related to the alphabetic character string on the entire width display screen (region C1 inFIG. 6( b)) while maintaining the display position (left aligned position) of the alphabetic character string in the region A1 (refer toFIG. 6( b)). - In Step S8, the
control unit 45 displays a single color display (for example, blackout and grayout) in the entire display region where the alphabetic character string is displayed (region E1 inFIG. 6( c)), while maintaining the display position (right aligned position) of the numeric character string on the display screen (refer toFIG. 6( c)). - In Step S9, the
control unit 45 determines whether or not an operation to delete a part of the character of either alphabetic character or numeric character is performed with theoperation unit 11. If the operation to delete is performed (YES), the process proceeds to Step S10. If the operation to delete is not performed (NO), the process in Step S9 is repeated again. - In step S10, when there is an operation to cancel an input (for example, cancellation of an operation to delete a part of a character string and cancellation of a soft key operation) immediately after either the alphabetic character string or the numeric character string is displayed, the
control unit 45 splits the display screen into upper and lower sides and returns the state to a state where both the alphabetic character string and the numeric character string are displayed. At this time, if the trigger of the return is a deletion operation, both the alphabetic character string and the numeric character string may be displayed in a state where one character at the end is deleted. - In Step S11, the
control unit 45 splits the display screen into right and left sides, and displays the alphabetic character string assigned to the operation key in the region H1 on the left part and displays the numeric character string assigned to the operation keys in the region J1 on the right part (refer toFIG. 7( a)), - In Step S12, the
control unit 45 determines whether an operation for selecting the display of the alphabetic character string or the numeric character string is performed. If the operation for selecting the display of the alphabetic character string is performed (YES), the process proceeds to Step S13. If an operation for displaying the numeric character string is performed (NO), the process proceeds to Step S14. - In Step S13, the
control unit 45 displays the display relating to the alphabetic character string on the entire width display screen (region K1 inFIG. 7( b)) by deleting the display of the numeric character string from the region J1 while maintaining the display position (left aligned position) of the alphabetic character string in region H1 (refer toFIG. 7( b)). - In Step S14, the
control unit 45 displays a single color display (for example, blackout and grayout) in the entire display region where the alphabetic character string is displayed (region M1 inFIG. 7( c)) while maintaining the display position (right aligned position) of the numeric character string on the display screen (refer toFIG. 7( c)). - In Step S15, the
control unit 45 determines whether or not an operation to delete a part of a character string of either the alphabetic character string or the numeric character string is performed with theoperation unit 11. If the operation to delete is performed (YES), the process proceeds to Step S16. If the operation to delete is not performed (NO), processing in Step S15 is repeated again. - In Step S16, when there is an operation to cancel an input (for example, an operation to delete a part of a character string, and cancellation of a soft key operation) immediately after only either one of the alphabetic character string and the numeric character string is displayed, the
control unit 45 splits the display screen into right and left sides and returns the state to a state where both the alphabetic character string and the numeric character string are displayed. At this time, if the trigger of the return is a deletion operation, both the alphabetic character string and the numeric character string may be displayed with one character at the end deleted. - As described above, in accordance with this embodiment, in a state where the display screen of the
display unit 21 is used horizontally, thecontrol unit 45 displays the first character kind character left aligned on the upper side in the display screen, and displays the second character kind character right aligned on a lower side in the display screen. Moreover, when a predetermined operation is performed by theoperation unit 11, thecontrol unit 45 maintains the display position of either one of the first character kind character and the second character kind character on the display screen according to the operated action, and deletes the display of the other one of the first character kind character and the second character kind character. Accordingly, since themobile telephone 1 displays either one of the first character kind character and the second character kind character, the user sees only either one of the first character kind character and the second character kind character. Therefore, themobile telephone 1 can shorten a view point movement distance of the user. - In addition, when an operation to adopt the display of the second character kind character is performed as the predetermined operation with the
operation unit 11, thecontrol unit 45 deletes the display of the first character kind character, and displays the second character kind character right aligned while maintaining the display position of the second character kind character on the display screen. Accordingly, since themobile telephone 1 displays the second character kind character and the display related to the second character kind character right aligned, a view point movement distance of the user can be shortened. - In addition, when an operation to display the second character kind character is performed with the
operation unit 11, thecontrol unit 45 displays a single color display in the entire display region where the first character kind character is displayed while maintaining the character display position of the second character kind character on the display screen. Accordingly, themobile telephone 1 can show clearly to the user that the first character kind character is not displayed. - In addition, the
control unit 45 splits the display screen into right and left sides, and displays the first character kind character left aligned on an upper part of the split left side display screen, and displays the second character kind character right aligned on a lower part of the split right side display screen. Alternatively, thecontrol unit 45 splits the display screen into upper and lower sides, and displays the first character kind character left aligned on an upper part of the split upper side display screen, and displays the second character kind character on a lower part of the split lower side display screen. Accordingly, themobile telephone 1 can display both the first character kind character and second character kind character as appropriate. - In addition, when a key for making a call is operated as the predetermined operation, the
control unit 45 deletes the display of the first character kind character while maintaining the display position of the second character kind character on the display screen. Accordingly, themobile telephone 1 can perform call making processing as appropriate. - In addition, when an operation to delete either one of the first character kind character and the second character kind character where the display is continued is performed with the
operation unit 11, thecontrol unit 45 returns the state to a state where both the first character kind character and the second character kind character are displayed on the display screen. Accordingly, since themobile telephone 1 returns the state to a state where both the first character kind character and the second character kind character are displayed again when a part of the character string of either the first character kind character or the second character kind character is deleted, the user does not need to input the first character kind character and the second character kind character again, and thus the operability of themobile telephone 1 improves. - Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and may be modified as appropriate. For example, although a
mobile telephone 1 having a plurality of physical operation keys has been described in the above embodiment, the present invention is not limited to this, and the present invention may be implemented on a mobile telephone that adopts a touch panel in thedisplay unit 21 and has virtual keys, for example. - It should be noted that, although the above embodiment has been shown using an example that distinguishes whether the state is a state where the display screen is used vertically or a state where the display screen is used horizontally by detecting a change in the relative position of the display
unit side case 3 to the supportingpart 4 b in an open state, in which the operationunit side case 2 and the displayunit side case 3 are connected, the present invention is not limited thereto. For example, in a case of a straight type terminal having a single non-interconnected case and a touch panel, whether the state is a state where the display screen is used vertically or a state where the display screen is used horizontally may be distinguished by installing an additional acceleration sensor or the like in the case and detecting the inclination state of the terminal. It should be noted that, in this case, the operation unit may be an operation unit having a plurality of operation keys where virtual operation keys that detect contacts to the operation keys are displayed in the touch panel, instead of a key switch that needs a physical pressing stroke. - In addition, although a
cellular telephone device 1 that serves as a mobile electronic device has been described in the above embodiment, the present invention is applicable to other mobile electronic devices.
